Compressed Natural Gas Vehicle Fueling Products
AGA/CGA NGV1CERTIFIED
ISO-9001 Certified
Snap-tite offers a full line of NGV1 fueling products.
“A World Class Tradition of Quality”
2
Snap-tite … Quality, Safety, Ingenuity
ounded over 65 years ago, Snap-tite has grown into a corporation producing
over 50 product lines in 8 facilities located in the United States and Europe. Starting
in the mid 1930’s and continuing through the latest developments, Snap-tite is widely
recognized for it’s role in problem solving for the military, aerospace, electronic cool-
ing, mobile equipment, offshore oil and gas, and natural gas appliance industries to
name a few.
Snap-tite has taken it’s expertise in design and manufacturing to develop
products for the compressed natural gas vehicle (NGV) market.
Snap-tite’s receptacles and patented nozzles fully comply with and are certified
to the ANSI/AGA/CGA NGV1 Standard for Compressed Natural Gas Vehicles
(NGV) fueling connection devices. Snap-tite has become the first to offer a range
of certified products to the market. The test was performed by Snap-tite (in AGA
certified Test Lab) and certified by the American Gas Association (AGA).
Snap-tite has been striving for the highest quality standards since our first
involvement in the space program in the early fifties. Snap-tite believes in continu-
ous improvement in all aspects of our operation from design and manufacturing to
customer service. Through a great deal of dedication and hard work, all of
Snap-tite’s divisions have become ISO-9001 Certified.
Safety is a prime concern to Snap-tite. Snap-tite has designed a feature into
the nozzle that makes it the safest design available. The nozzle cannot be manu-ally disconnected from the receptacle while under internal pressure greater than 350 psi (24 bar). Snap-tite has done extensive testing of numerous designs
and demonstrated a very unsafe condition with respect to “kick back” of the nozzle
which can cause personal injury when disconnected at internal pressures greater than
350 psi (24 bar). In addition, this can cause a “washout” of the receptacle seal. An
operator may not know of this failure and when a nozzle is again connected to the
receptacle excessive leakage occurs with the possibility of a fire or explosion. This
feature of the Snap-tite nozzle exceeds the requirements of the NGV1 specification
and has been assigned a world wide patent.

Featuresï=Lightweight – .96 lbs. (.435 kgs)
ï=The bumper is made of a durable polyurethane to reduce wear and damage to vehicles and to protect the user from the cold temperature of the nozzle
ï=The bumper is designed for rugged use, it protects the front engagement bore and provides a very comfortable grip when connecting or disconnecting
ï=Color coded bumper visually identifies the service pressure – blue for 3,000 psi (207 bar), yellow for 3,600 psi (248 bar)
ï=Connects with single handed operation by pushing together
ï=Disconnects with single handed operation by pulling back on the polyurethane bumper
ï=The Snap-tite patented nozzle cannot be manually disconnected from the receptacle at an internal pressure greater than 350 psi (24 bar)
ï High reliability ball locking
ï=Poppet valve prevents the inadvertent flow of gas when the nozzle is disconnected
ï=Keying system prevents higher pressure nozzle from connecting onto lower pressure receptacle
ï=Nozzles available in either 316 Stainless Steel
ï=When connected to the receptacle the nozzle body extends over the outside diameter of the recep- tacle thus providing an excellent length to diameter ratio (L/D)
ï=All materials utilized by Snap-tite guarantee a very weather resistant device considering ambient temperature, solar radiation, humidity, atmospheric toxins and airborne salt
Snap-tite’s nozzle
is designed specifical-
ly for the transfer of
compressed natural gas
(CNG) to natural gas
vehicles.
This nozzle can be
used for fast fill or time
fill in a self depressur-
izing fueling system or
in conjunction with a
3-way valve attached.
Snap-tite’s nozzle
also allows complete
interchangeability to any
receptacle con- forming
to the NGV1 require-
ments.

breakaway is designed
specifically for com-
pressed natura l g as
fueling systems. When
properly installed, this in-
line breakaway allows for
the safe disconnection
from the fueling system
without damage to the
dispenser in the event of
an accidental disconnect
(drive-off). The inline
breakaway was designed
to replace the traditional
tripod leverage towers
used in conjunction with
the ISO B style coupling
as the breakaway connec-
tion for the fueling hose
from the dispenser.
